Cross browser history sync

Question

Is it possible to have sync browser history in major browsers (Google Chrome, Internet Explorer, Firefox, Safari, etc) continuously. I have looked online for addons or ideas but nothing. I know all browsers have some sort of database that store links visited, how would one sync all in a way if I am in Firefox I am still able to see Internet Explorer history?

Answer 1

Firefox, Chrome and Safari all use sqlite database files that you can query. Here is a link with a few commands to print browser history. Link

And here is a link to someone who created a script to import Safari history to Chrome. Link

So it should be possible to create a script that could sync at least those browsers.
